Breachway May 2026

Skip it if you hate RNG or prefer real-time action.

You command a spaceship trying to survive a perilous journey through a fractured galaxy. Every jump, every choice, and every card you play matters. Combat is turn-based and card-driven—your ship’s systems (weapons, shields, engines) are represented by cards you draw and play each turn. Position your ship, manage your energy, and chain powerful combos to tear enemy vessels apart. Breachway

Developed by and published by Hooded Horse , Breachway just dropped into Early Access, and it’s already shaping up to be something special. Skip it if you hate RNG or prefer real-time action

8.5/10 – A promising launch with a unique blend of genres. If they flesh out the mid-game and add more events, it could be a classic. Have you played Breachway yet? What’s your favorite ship build so far? Let me know below. manage your energy

Breachway is currently $19.99 USD on Steam (10% launch discount often active). The devs are active on Discord and have a roadmap through 2025.

 

Hardware Installation & Configuration

Installation Steps
  

  • Check the parallel printer port setting in the bios, it should be EPP or Normal.
  • Check there are any active resident programs that use the printer port, such as TWAIN drivers. You may have to remove it.
  • Connect one end of the 25 pin SubD parallel cable  to PC printer port
  • Connect the other end  of parallel cable to 25 Pins port of the programmer
  • Connect USB power cable or AC adaptor (Note: if you are working on the EPROM programming. You may need use a AC adaptor, so that you can get Vcc 5.6V and 6.2V when doing programming)
  • The yellow power normal indicator of the programmer should light up, then the programmer power supply is normal.
  • Run the software
  • Select devices type
  • Click the Willem in toolbar to change to PCB3
  • Set the DIP switch based on the displayed pattern.

          (Note: the LPT port of PC MUST set to ECP or ECP+EPP during BIOS setup. To enter the BIOS setting mode, you need press "Del" key or "F1" key during the computer selftest, which is the moment of computer just power up.)

 

Software Version To Use

The software can be download from download.mcumall.com  

There are board hardware selection jumper on the board. When set the jumper to PCB3B, then user have to use 0.97ja and before version software.

If the board selection set to PCB3.5, PCB5.0, PCB5.5C, then the software 0.98D6 should be used.

Hardware Check

After start the program, click test hardwar under Help menu. If the connection and power supply is normal, then appears: "Hardware present"   Otherwise check if the programmer connects well with PC, or power supply is normal.

 

Jumper Configuration

 

PCB3.5/PCB4E

Breachway  
(Two PLCC32 adapter is not applied on the PCB4E)

 

PCB5.0

Breachway

 

PCB5.5C

 

Breachway

Note: the Vcc setting jumper only has effect when you are using AC adaptor as power source. For the USB power only 5V Vcc is available.

For the PCB5.5C, set DIP steps:

1. press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF.

2. press DIP Bit shift button to shift the DIP bit position to where need to set. And then press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF.

3. Repeat those steps till all DIP bit ae set  same as software indicated.

For PCB5.5C voltage and Special chip selection:

1. Put back the safety jumper.

2. Press the voltage button and hold for 1 second, the voltage LED should move to next. Repeat till desired voltage LED light up.

3. Press the chip selection button and hold for 1 second, the chip LED should move to next. Repeat till desired LED light up.

4. Remove the safety jumper to lock the selected voltage and chip selection

 

DIP Switch (PCB3.5, PCB5.0)

When programming one chip,  follow the program prompt to set DIP switch .
